Achievements
Sixteen trophies across four tiers — five easy, five medium, five hard, and one that's deliberately, almost unfairly difficult. Everything's tracked automatically in your browser the moment you earn it, no account required. They're saved locally on this device, so a different browser or phone starts its own trophy case.
Easy
Land these in your first game or two just by playing normally.
Medium
These take a real run — a bit of streak discipline, or a few sessions.
Hard
Reserved for genuinely strong runs. Most players will need several attempts.
Impossible
One trophy, and it's here on purpose. Beating a shuffled 52-card deck once already takes a cooperative deck and clean play — doing it twice in a row, back to back with no loss in between, multiplies that luck against itself. Most players will never unlock this one, and that's the point.
Tips for the harder ones
Building a card streak of 10 or 20
Needs one card position to survive that many correct guesses in a row without switching away entirely. Cards dealt near 2 or Ace hold their probability edge the longest, so they're the best candidates to start one. See the Strategy Guide for how to protect a hot card once its value drifts somewhere risky.
Reaching a global streak of 25
This is well past the 2× multiplier threshold at 15 — you're deliberately pushing further after the reward has already maxed out, purely to prove you can hold it. Treat every guess like your mistake budget is zero once you're this deep.
Beating the deck with three or fewer mistakes
Requires clearing all 52 cards while spending less than a third of your normal mistake budget. Save your mistakes for the back third of the deck rather than the front, and skip anything resembling a coin flip once you're past mistake two.
Beating the deck twice in a row
There's no strategy that reliably produces this — it needs two independently cooperative shuffles plus clean play across both. Play a lot, play well, and treat it as a bonus if it ever happens rather than a goal to chase directly.
